I should also mention that when everything is plugged in as normal i still have no power to those switches.Any help or suggestions would be great.
Time to break out the multi-meter and start checking for where the power stops. I would start with the door quick disconnect, suspecting water intrusion and corrosion. A very common issue on older Acadia's.

Clicking noise is most likely a relay. Could me a normal indication that juice is making it to the relay.
